Swimming Pool Stair Repair & Step Resurfacing

Pool stairs are the one part of a swimming pool that virtually every swimmer interacts with every single time they enter or exit the water. They're also one of the most structurally complex parts of a gunite or concrete pool — and one of the most common areas of deterioration. Rough, crumbling, or structurally compromised pool steps are both a comfort problem and a genuine safety risk. At Total Design Concrete LLC, we restore damaged pool stairs using polymer concrete systems that return them to smooth, safe, structurally sound condition — without tearing out and rebuilding the entire stair structure.

Common Pool Stair Problems We Fix

After 35+ years of pool restoration work throughout New England, we've seen every type of stair deterioration. The most common issues we address:

Surface Roughness and Plaster Wear

The plaster surface on pool stairs wears faster than the rest of the pool interior because it endures constant mechanical abrasion from feet, sandals carried accidentally into the pool, and cleaning equipment. The leading edge of each step tread — the nosing — is typically the first area to wear through to bare gunite. Bare gunite is extremely rough and abrasive. Swimmers get cuts and abrasions from stepped-on tread edges, and the problem accelerates as more surface erodes.

Cracks in the Step Structure

Gunite pool stairs are monolithic — cast as part of the pool shell — and are susceptible to the same cracking mechanisms as the rest of the shell. Thermal stress, ground movement, and freeze-thaw cycling all create crack pathways through the stair structure. Hairline cracks that reach the pool water allow chemical infiltration that accelerates internal deterioration over time.

Hollow or Delaminated Plaster

Plaster over pool stairs can delaminate from the underlying gunite, creating hollow spots that eventually crack and spall. This is often caused by water infiltrating behind the plaster through cracks or porous areas, particularly during winter when the pool is empty or partially drained and freeze-thaw cycles repeatedly stress the bond.

Eroded or Missing Step Nosing

The rounded nosing at the leading edge of each step is the most abused surface in the pool. It's the first thing swimmers step on getting in and the last thing they push off from getting out. Worn or missing nosing isn't just unsightly — it makes the depth transition harder to judge and increases the risk of slipping when entering the pool.

Staining That Won't Clean

Steps accumulate more biological material than the surrounding pool walls — algae, calcium scale, and organic staining settle in the corners and texture of step surfaces. When staining penetrates the plaster matrix rather than sitting on the surface, normal cleaning and acid treatments don't resolve it fully.

The Polymer Concrete Stair Restoration Process

Our pool step resurfacing process begins with a thorough mechanical preparation of the existing stair surfaces — removing all loose, delaminated, or deteriorated plaster, grinding the existing surface profile to create bonding roughness, and repairing any structural voids or cracks in the gunite beneath. This preparation step is where most of the work happens, and it's where shortcuts create failures.

Once the substrate is properly prepared, we apply polymer-modified plaster or overlay material to rebuild the stair surfaces to correct geometry and proper thickness. Step nosings are reformed with crisp edges, step faces and treads are rebuilt to uniform profiles, and the finished surface integrates seamlessly with the surrounding pool interior plaster. See our pool plaster restoration page for more on the interior plaster systems we use.

The result is pool stairs that feel solid underfoot, have smooth tread surfaces that won't cut feet, and are visually consistent with the rest of the restored pool interior. Our gunite pool stair restoration eliminates the need to reconstruct the stair structure — which would require demolition, new rebar, new gunite application, and significantly higher cost.

Stair Repair as Part of a Complete Pool Renovation

Pool stair repair is rarely a standalone project. In most cases, the same deterioration that has affected the stairs has also affected the surrounding pool plaster, the waterline tile, the coping, or the deck. We typically evaluate the entire pool when assessing the stairs, because addressing everything together in a single project is more efficient and delivers a consistent finished result.

If your pool stairs need work, there's a good chance the adjacent surfaces do too. An honest evaluation from Total Design Concrete LLC will tell you exactly what's needed — and what isn't.
